Description

Detachable insulated container Technical Field

[0001] This invention relates to the field of thermal insulation container technology, and specifically to a detachable thermal insulation container. Background Technology

[0002] In daily life, insulated containers, such as thermos flasks and cups, are commonly used beverage containers, especially in situations where it is necessary to keep drinks at a warm temperature, such as at home, in the office, or during outdoor activities. Traditional insulated containers usually consist of a lid and a body, and their spout design is often quite simple, lacking an effective water flow guiding structure, which makes it easy for drinks to splash when poured, causing inconvenience.

[0003] Furthermore, the lids of traditional insulated containers have relatively simple structures and lack multifunctional designs. For example, the lid usually just covers the body of the container without an effective sealing and opening mechanism, which limits the heat preservation effect and makes it inconvenient for users to operate.

[0004] Furthermore, the spout of traditional insulated containers is usually molded as a single piece with the body, making it difficult to disassemble and clean. Over time, this can lead to the accumulation of dirt and bacteria, affecting the hygiene and safety of beverages. At the same time, this one-piece design also limits the shape and function of the spout, failing to meet the diverse needs of users.

[0005] To address these issues, some detachable insulated containers have begun to appear on the market, with lids and bodies that can be separated for easy cleaning and maintenance. However, these products still have many shortcomings in terms of spout design, lid versatility, and grip connection. For example, the spout lacks an effective water flow guiding structure, making it easy for water to splash when pouring; the lid lacks a convenient opening and closing mechanism, making operation less user-friendly; and the connection between the grip and the body is not secure enough, making it prone to loosening or detachment.

[0006] Therefore, there is an urgent need for a new type of detachable insulated container with a spout design that effectively guides water flow and reduces splashing; a multi-functional lid design that facilitates user operation and maintenance; and a more secure and reliable connection between the grip and the container body, meeting diverse user needs. This invention is proposed based on this background technology. Summary of the Invention

[0007] The purpose of this invention is to provide a detachable insulated container. By improving the design of the lid and spout, this invention solves the shortcomings of traditional insulated containers in terms of water output control, sealing performance, disassembly and cleaning, and ease of operation.

[0008] To solve the above-mentioned technical problems, the present invention provides a detachable insulated container, including a lid and a body.

[0009] A combined spout is provided between the pot body and the pot lid, and the combined spout is installed at the upper opening of the pot body.

[0010] The combined spout includes a mounting body, which is provided with a gripping part and a flow guiding part.

[0011] The guide section cooperates with the outlet to guide the direction of water flow. The guide section includes a guide plate, and the two side plates of the guide plate are folded upward to form a guide channel including a central guide channel and two side guide channels. This makes the water flow form a dispersed flow when it flows out of the outlet, and converges from the outlet in the direction of water flow through the central guide channel and the side guide channels.

[0012] In addition to the above-mentioned technical features, this application also makes improvements in the following aspects:

[0013] In some embodiments, the lid includes an upper lid and a lower lid, both of which are hollow inside, and the upper lid is fastened to the upper part of the lower lid.

[0014] The lid is configured as an umbrella-shaped or columnar structure, and a cap is provided on the upper part of the lid, which is connected to the upper lid body through a connecting hole.

[0016] The kettle lid is equipped with a switch handle. One end of the switch handle is a free end, and the other end is a connecting end. A hinge shaft is provided on the connecting end. The hinge shaft passes through the through hole in the upper part of the lid and extends into the hollow part inside the kettle lid. It is hinged to the mounting plate inside the upper lid body through the hinge shaft, and the hinge shaft can move up and down along the mounting groove. Pressing the free end of the switch handle will open the water outlet.

[0017] In some embodiments, the switch handle is configured with a Z-shaped structure, and the switch handle is provided with a pressing part and an abutting part, and the bottom of the abutting part is provided with a limiting groove.

[0018] In some embodiments, the lower cover includes a first cylindrical segment, a conical segment, a second cylindrical segment, and a transition segment.

[0019] The first cylindrical segment and the conical segment together form a trumpet-shaped cavity structure, and an annular groove is provided at the opening of the first cylindrical segment.

[0020] The second cylindrical segment has external threads on its exterior and is recessed inward to form a cylindrical cavity, which is located directly above the opening of the pot body.

[0021] The cylindrical cavity is provided with a water outlet and an air vent on both sides, which are located on the same horizontal plane and are arranged to run through the cylindrical cavity in the radial direction.

[0022] A guide sleeve is provided at the center of the cylindrical cavity. The guide sleeve passes through the cylindrical cavity and extends into the trumpet-shaped cavity, and the diameter of the upper opening of the guide sleeve is smaller than the diameter of the lower opening.

[0023] In some embodiments, a valve assembly is installed at the center of the lower cover for opening and closing the water outlet.

[0024] The valve body assembly includes a valve plug and a valve stem. One end of the valve stem is connected to the valve plug, and the other end passes through a guide sleeve provided in the center of the cylindrical cavity and abuts against the abutting part of the switch handle. The upper end of the valve stem extends into the limiting groove provided in the abutting part.

[0025] The valve plug is sealed at the lower opening of the cylindrical cavity, and a sealing ring is provided around the valve plug.

[0026] In some embodiments, the mounting body includes a tapered opening section, a threaded connection section, and a mounting section, and the mounting body as a whole has a constricted structure that is larger at the top and smaller at the bottom.

[0027] The tapered opening section mates with the upper cover, and the threaded connection section is used to connect the lid.

[0028] An annular retaining ring is provided between the threaded connection section and the installation section to limit the installation position of the lower cover.

[0029] During installation, the transition section of the lower cover extends into the annular limiting ring between the threaded connection section and the installation section, and works in conjunction with the annular sealing ring circumferentially set in the transition section to form a sealing structure at the opening of the lower cover and the pot body.

[0030] In some embodiments, the inner wall of the mounting section is provided with limiting blocks along its circumferential direction. Multiple limiting blocks are provided and arranged in an array for engaging with the opening of the kettle body, thereby installing the mounting body at the opening of the kettle body.

[0031] In some embodiments, the mounting section of the mounting body is connected to the kettle body by a snap-fit ​​or threaded connection, and the mounting section can be used to mount the kettle body or bottle body.

[0032] In some embodiments, the gripping part has an overall curved structure, with one end connected to the mounting body and the other end being the pot body connection end.

[0033] The kettle body connection end is provided with a connection component, including a connection block and a locking element, which is used to achieve a locking connection between the gripping part and the kettle body.

[0034] By adopting the above-described technical solution, the present invention possesses at least one of the following beneficial effects:

[0035] 1. Improved pouring smoothness and accuracy

[0036] The unique flow guide design of the modular spout is key to achieving smooth and precise pouring. Its central and side flow guide channels, formed by the flow guide plate, initially disperse the water flow from the outlet before it converges orderly through the channels towards the outlet. This design effectively avoids the concentrated spraying or splashing that can occur with traditional containers. Users can more precisely control the direction and flow rate, making it easy to pour slowly or quickly, greatly reducing the risk of spillage and improving convenience and hygiene.

[0037] 2. Enhanced stability of the connection between the lid and the body of the teapot.

[0038] The mounting bracket plays a crucial role in connecting the lid and the body of the kettle. Its unique constricted neck structure and meticulously designed connecting sections, such as the reliable connection between the threaded section and the lid, and the locking mechanism between the mounting section and the kettle body opening via a limiting block, ensure a stable connection between the lid and the kettle body. In daily use, whether the container is moved, placed, or subjected to minor external impacts, the lid is unlikely to accidentally detach or loosen, effectively preventing heat loss and liquid leakage. This provides a solid structural foundation for the container's insulation performance and enhances the overall durability and reliability of the product.

[0039] 3. Improved ease of opening and closing and sealing of the water outlet.

[0040] The linkage design between the switch handle and the valve body assembly enables convenient and efficient opening and closing of the water outlet. The Z-shaped switch handle's pressing part facilitates easy force application by the user. The Z-shaped design and the up-and-down movement of the hinge shaft allow users to simply press to open or close the water outlet, making operation simple and quick. At the same time, the ergonomic design of the switch handle improves user comfort and reduces fatigue during operation.

[0041] When the free end is pressed, the hinge shaft moves up and down within the mounting slot of the mounting plate, driving the valve stem to move and precisely control the opening and closing of the valve plug at the outlet. The circumferential sealing ring of the valve plug and the cooperation of the guide sleeve ensure good sealing of the outlet in the closed state, effectively preventing heat loss through the outlet and maximizing the insulation time of the insulated container to meet users' needs for long-term insulation. At the same time, the operation is smooth and seamless during opening and closing, without any jamming or effort, providing users with a comfortable and convenient user experience.

[0042] 4. Expanding Universality and Adaptability

[0043] The mounting section of the main body can be connected to various kettle or bottle bodies, a feature that greatly expands the product's versatility. Users can easily install the modular spout onto containers of different sizes or types according to different usage scenarios and needs, achieving flexible integration and utilization of resources and reducing inconvenience or additional purchase costs caused by container incompatibility. Whether for daily home use, outdoor travel, or office environments, the detachable insulated container of this invention better adapts to various situations, providing users with more choices and convenience.

[0044] 5. Improved grip comfort and safety

[0045] The curved structure and connecting components of the grip are designed with user comfort and safety in mind. The curved shape conforms to the natural shape of the human hand, making it more comfortable and natural to hold, reducing hand fatigue. The connecting components at the kettle body connection end, including the connecting block and locking element, ensure a tight and secure connection between the grip and the kettle body. During the lifting of the container, the grip provides a stable and reliable point of force, effectively preventing the container from slipping. Even when the container is full of liquid and heavy, users can operate it easily and safely, further enhancing the product's practicality and user-friendliness.

[0046] In summary, the detachable insulated container of this invention, through its innovative structural design and the coordinated operation of its components, has achieved significant technical improvements in many aspects, including water pouring performance, connection stability, ease of opening and closing, versatility, and grip experience. It provides users with a high-quality, multifunctional, safe, and reliable insulated container solution, with broad market application prospects and significant social benefits.

Unless otherwise defined, the technical or scientific terms used in this invention should be understood in their ordinary sense by those skilled in the art.

[0059] The terms "a," "an," "an," "the," and similar words used in this invention do not indicate quantity limitation and can represent singular or plural. The terms "comprising," "including," "having," and any variations thereof used in this invention are intended to cover non-exclusive inclusion; the terms "first," "second," "third," etc. used in this invention are merely to distinguish similar objects and do not represent a specific ordering of objects.

[0060] Traditional insulated containers often lack effective water flow guidance in their spout designs, leading to easy splashing of beverages when pouring and negatively impacting the user experience. Furthermore, the simple lid structure lacks convenient opening and closing mechanisms, limiting insulation performance and making operation cumbersome. In addition, the one-piece design of the spout and body is not only difficult to clean, easily fostering bacterial growth, but also limits the versatility of the spout's functions. Although detachable insulated containers have emerged on the market, significant shortcomings remain in areas such as water flow control of the spout, multi-functional lid design, and a secure connection of the gripping mechanism.

[0061] Based on the above problems, this invention proposes a novel detachable insulated container that integrates water flow guidance, a multi-functional lid, an easy-to-disassemble and clean spout, and a stable gripping part. The technical solution, working principle, and technical effects of this invention will be described in detail below with reference to specific embodiments.

[0062] Referring to Figures 1, 2, and 5, the present invention describes a detachable insulated container, including a pot body 1 and a pot lid 2.

[0063] As shown in Figures 2, 4, and 6, a modular spout 3 is provided between the kettle body 1 and the lid 2. The modular spout 3 is installed at the upper opening of the kettle body 1. The design of the modular spout 3 allows the spout to be easily disassembled and assembled with the kettle body 1, facilitating cleaning and maintenance.

[0064] As an optimization solution, the combined spout 3 is provided with a gripping part 32 and a flow guiding part 33. The gripping part 32 makes it easy for users to hold and pour, while the flow guiding part 33 works with the water outlet 52 to guide the direction of water flow.

[0065] Specifically, the flow guide 33 includes a flow guide plate 331, the two side plates of which are folded upward to form a flow guide channel including a central flow guide channel 332 and two side flow guide channels 333. This design causes the water flow to form a dispersed flow when it flows out of the outlet 52, and converges from the outlet 52 in the direction of water flow through the central flow guide channel 332 and the side flow guide channels 333, thereby avoiding the risk of water splashing and scalding users.

[0066] Furthermore, as shown in Figures 2 and 3, the lid 2 includes an upper lid body 21 and a lower lid body 22. The upper lid body 21 and the lower lid body 22 are hollow inside, and the upper lid body 21 is fastened to the upper part of the lower lid body 22. The lid 2 is designed with an umbrella-shaped or columnar structure, which is not only aesthetically pleasing but also increases the stability of the lid 2.

[0067] A cap 23 is also provided on the upper part of the lid 2. The cap 23 is connected to the upper lid body 21 through the connecting hole 24, which makes it convenient for the user to open and close the lid 2.

[0068] A through hole 25 is provided on the upper part of the upper cover 21, and a mounting plate 26 is provided thereon, on which a mounting groove 27 is provided. The lid 2 is also provided with a switch handle 4, one end of which is a free end 41, and the other end is a connecting end 42.

[0069] A hinge shaft 43 is provided on the connecting end 42. The hinge shaft 43 passes through the through hole 25 on the upper part of the upper cover 21 and extends into the hollow part inside the lid 2. It is hinged to the mounting plate 26 inside the upper cover 21 through the hinge shaft 43.

[0070] The hinge shaft 43 can move up and down along the mounting groove 27, allowing the user to open or close the outlet 52 by pressing the free end 41 of the switch handle 4, making the operation simple and quick.

[0071] To facilitate water dispensing, the switch handle 4 is designed with a Z-shaped structure, which not only makes it easier for users to hold and operate, but also increases the stability of the switch handle 4.

[0072] The switch handle 4 is also provided with a pressing part 44 and an abutting part 45, and the bottom of the abutting part 45 is provided with a limiting groove 46. This design enables the switch handle 4 to stably transmit force to the valve body assembly 6 during the pressing process, thereby realizing the opening and closing of the water outlet 52.

[0073] The lower cover 22 includes a first cylindrical section 221, a conical section 222, a second cylindrical section 223, and a transition section 224.

[0074] The first cylindrical section 221 and the conical section 222 together form a trumpet-shaped cavity structure, which facilitates the smooth flow of water. The second cylindrical section 223 has external threads on its exterior for threaded connection with the pot body 1.

[0075] The interior of the second columnar segment 223 is recessed inward to form a columnar cavity 51, which is located directly above the opening of the pot body 1.

[0076] An outlet 52 and an vent 53 are respectively provided on both sides of the cylindrical cavity 51. The outlet 52 is used to discharge the liquid in the insulated container, while the vent 53 is used to discharge the air in the container, forming an annular airflow between the outlet 52 and the vent 53, thereby maintaining the pressure balance inside and outside the container. A guide sleeve 54 is also provided in the center of the cylindrical cavity 51. The guide sleeve 54 passes through the cylindrical cavity 51 and extends into the funnel-shaped cavity to further guide the water flow.

[0077] A valve assembly 6 is installed at the center of the lower cover 22 for opening and closing the outlet 52.

[0078] The valve body assembly 6 includes a valve plug 61 and a valve stem 62. One end of the valve stem 62 is connected to the valve plug 61, and the other end passes through the guide sleeve 54 provided in the center of the cylindrical cavity 51 and abuts against the abutting part 45 of the switch handle 4.

[0079] The upper end of the valve stem 62 extends into the limiting groove 46 provided in the abutment part 45, so that the switch handle 4 can stably drive the valve plug 61 to move during the pressing process, thereby realizing the opening and closing of the water outlet 52.

[0080] The valve plug 61 is sealed at the lower opening of the cylindrical cavity 51, and a sealing ring 63 is provided around the valve plug 61, which increases the sealing between the valve plug 61 and the cylindrical cavity 51.

[0081] The mounting body 31 includes a tapered opening section 311, a threaded connection section 312, and a mounting section 313, and the mounting body 31 as a whole has a constricted structure that is larger at the top and smaller at the bottom.

[0082] The tapered opening section 311 mates with the upper cover body 21, and the threaded connection section 312 is used to connect the lid 2.

[0083] An annular retaining ring 314 is provided between the threaded connection section 312 and the installation section 313 to limit the installation position of the lower cover 22.

[0084] As shown in Figures 2 and 4, during installation, the transition section 224 of the lower cover 22 extends into the annular retaining ring 314 between the threaded connection section 312 and the mounting section 313, and cooperates with the annular sealing ring 63 circumferentially arranged on the transition section 224 to form a sealing structure at the opening of the lower cover 22 and the pot body 1. This design not only increases the sealing performance of the insulated container, but also allows the lower cover 22 to be stably installed on the pot body 1.

[0085] The inner wall of the mounting section 313 is provided with limiting blocks 315 along its circumferential direction. Multiple limiting blocks 315 are provided and distributed in an array. These limiting blocks 315 engage with the opening of the kettle body 1, further installing the mounting body 31 at the opening of the kettle body 1. This engaging design increases the connection stability between the mounting body 31 and the kettle body 1.

[0086] As shown in Figures 2 and 8, the mounting section 313 of the mounting body 31 can be connected to the kettle body 1 by means of snap-fit ​​or threaded connection. The mounting section 313 can be used to mount the kettle body 1 or the bottle body 8.

[0087] The gripping part 32 has a curved structure, with one end connected to the mounting body 31 and the other end being the pot body connection end 42.

[0088] As shown in Figures 2, 6, and 7, a connecting component 7, including a connecting block 71 and a locking element 72, is provided at the connecting end 42 of the kettle body. This design allows the gripping part 32 to be easily locked to the kettle body 1, increasing the overall stability of the insulated container. At the same time, the curved structure of the gripping part 32 is also ergonomically designed, making it easy for users to hold and pour.

[0089] In summary, the detachable insulated container of the present invention solves the problems existing in existing insulated containers and improves the user experience through its innovative combination spout 3 design, multi-functional lid 2 structure, stable valve body assembly 6, and user-friendly gripping part 32 design.

[0090] In conjunction with the above description of the specific structure of the detachable insulated container of the present invention, the following explanation is provided to more clearly illustrate the assembly method of the detachable insulated container of the present invention:

[0091] I. Material Selection

[0092] In this embodiment, the kettle body 1 is made of stainless steel, which has good heat preservation performance and strength, can effectively maintain the temperature of the internal liquid and withstand a certain amount of external impact. It is made through stretching and forming processes to ensure that the surface of the kettle body 1 is smooth and flawless, and the internal cavity has good sealing performance.

[0093] The upper lid 21 and lower lid 22 of the kettle lid 2 are both made of a combination of food-grade plastic and stainless steel. This material is lightweight, does not conduct heat well, and has a certain degree of toughness and wear resistance. The cap 23 is also made of stainless steel, echoing the material of the kettle body 1, enhancing the overall aesthetics and durability.

[0094] The mounting body 31 of the combined spout 3 is made of high-strength engineering plastic injection molding, which can meet the structural strength requirements while facilitating the processing of various complex shapes.

[0095] The gripping part 32 is covered with a silicone material that is soft, comfortable to the touch, and has anti-slip properties, which can effectively prevent it from slipping out of your hand during gripping.

[0096] The valve plug 61 of the valve body assembly 6 is made of rubber, which has good sealing performance and elasticity, and can fit tightly against the lower opening of the cylindrical cavity 51 to prevent liquid leakage. The valve stem 62 is made of hard rubber or stainless steel to ensure that it is not easily deformed or damaged during frequent opening and closing operations.

[0097] II. Installation of the combined spout 3

[0098] Align the mounting section 313 of the mounting body 31 of the combined spout 3 with the upper opening of the kettle body 1, and engage it with the slots at the opening of the kettle body 1 using multiple limiting blocks 315 on the inner wall of the mounting section 313. During engagement, slightly rotate the mounting body 31 to allow the limiting blocks 315 to slide smoothly into the slots until the mounting body 31 is fully installed. At this point, the threaded connection section 312 of the mounting body 31 is located above the opening of the kettle body 1, ready to be connected to the kettle lid 2.

[0099] III. Assembly of the lid (2 pieces)

[0100] Assemble the first cylindrical section 221, the conical section 222, the second cylindrical section 223, and the transition section 224 of the lower cover 22.

[0101] Fabrication of the lower cover 22: A standard external thread is machined on the outside of the second cylindrical section 223 of the lower cover 22. An inwardly recessed cylindrical cavity 51 is formed inside by a stamping process. A water outlet 52 and an exhaust hole 53 are machined on both sides of the cylindrical cavity 51. A guide sleeve 54 is installed in the center of the cylindrical cavity 51. The guide sleeve 54 passes through the cylindrical cavity 51 and extends into the trumpet-shaped cavity. The diameter of the upper opening of the guide sleeve 54 is smaller than the diameter of the lower opening so that the valve stem 62 can move up and down smoothly in it.

[0102] Install valve body assembly 6: Install valve plug 61 at one end of valve stem 62, install sealing ring 63 around valve plug 61, and then pass the other end of valve stem 62 through guide sleeve 54 in the center of cylindrical cavity 51, so that valve plug 61 seals the lower opening of cylindrical cavity 51.

[0103] Assemble the upper cover 21: A through hole 25 is made in the upper part of the upper cover 21, and a mounting plate 26 with a mounting groove 27 is installed inside. The hinge shaft 43 of the connecting end 42 of the switch handle 4 passes through the through hole 25 in the upper part of the upper cover 21 and extends into the hollow part inside the lid 2, so that the hinge shaft 43 mates with the shaft hole on the mounting plate 26, thereby realizing the hinge connection between the switch handle 4 and the upper cover 21, and ensuring that the hinge shaft 43 can move smoothly up and down along the mounting groove 27.

[0104] The upper cover 21 is fastened onto the upper part of the lower cover 22, so that the upper cover 21 and the lower cover 22 fit tightly together. Then, the cap 23 is connected to the upper cover 21 through the connecting hole 24. It can be fixed by screws or by snap-fit ​​connection to ensure that the cap 23 is installed firmly.

[0105] IV. Overall Assembly

[0106] The assembled lid 2 is connected to the mounting body 31 of the pre-installed combined spout 3 on the kettle body 1 via the threaded connection section 312.

[0107] Rotate the lid 2 so that the threads of the lid 2 are tightly engaged with the threads of the mounting body 31 until the lid 2 is installed in place. At this time, the transition section 224 of the lower lid body 22 extends into the annular limiting ring 314 between the threaded connection section 312 and the mounting section 313 of the mounting body 31, and is in close contact with the annular sealing ring 63 circumferentially provided in the transition section 224, forming a good sealing structure to prevent heat from being lost from the connection between the lid 2 and the body 1.

[0108] The opening and closing function of the outlet 52 is tested. Press the free end 41 of the switch handle 4 and observe whether the valve stem 62 can move smoothly up and down in the guide sleeve 54, and whether the valve plug 61 can accurately open and close the outlet 52. At the same time, check the water flow guidance when the outlet 52 is open, and observe whether the water flow forms a dispersed flow when flowing out of the outlet 52 according to the design of the guide part 33, and converges from the outlet 52 towards the water outlet direction through the central guide groove 332 and the side guide groove 333. Check whether the water flow is uniform and stable, and whether there is any splashing.

[0109] If any problems are found, such as excessive friction between components or poor water flow, the corresponding components should be adjusted or optimized. For example, the shape of the guide plate 331 should be fine-tuned, and the fitting accuracy between the valve stem 62 and the guide sleeve 54 should be corrected, until all functions of the entire insulation container meet the design requirements.

[0110] This invention provides a detachable insulated container suitable for various scenarios, including household use, outdoor sports, and office environments. The application details for these three scenarios are described below:

[0111] I. Everyday Home Use Scenarios

[0112] In a typical household setting, this detachable insulated container can be used to store hot water, making it convenient for family members to drink whenever they want.

[0113] The kettle body 1 is made of stainless steel, which has good heat retention properties. The mounting body 31 of the modular spout 3 is tightly connected to the lid 2 via a threaded connection section 312. The guide channel design of the flow guide 33 ensures that the water flows smoothly and does not splash when pouring hot water.

[0114] The curved structure of the gripping part 32 makes it more comfortable for users to pick up the insulated container, and the connecting component 7 ensures a firm connection between the gripping part 32 and the pot body 1. It can be operated safely even when the pot is full of hot water.

[0115] Container assembly and initial state:

[0116] First, connect the mounting body 31 of the combined spout 3 to the kettle body 1. Align the mounting section 313 of the mounting body 31 with the upper opening of the kettle body 1, and gently rotate and engage it with the opening of the kettle body 1 using the multiple arrayed limiting blocks 315 on the inner wall of the mounting section 313, so that the mounting body 31 is firmly fixed to the kettle body 1. At this time, the transition section 224 of the lower cover 22 extends into the annular limiting retaining ring 314 between the threaded connection section 312 and the mounting section 313 of the mounting body 31, and forms a good sealing structure under the action of the annular sealing ring 63 around the transition section 224.

[0117] Next, assemble the upper lid 21 and lower lid 22 of the lid 2. The upper lid 21 is fastened onto the upper part of the lower lid 22, ensuring that the hollow parts inside both fit together. Then, the cap 23 is connected and fixed to the upper lid 21 through the connecting hole 24.

[0118] On the lid 2, the hinge shaft 43 of the switch handle 4 passes through the upper through hole 25 of the upper cover 21 and is hinged to the internal mounting plate 26. The valve plug 61 connected to one end of the valve stem 62 seals the lower opening of the cylindrical cavity 51 of the lower cover 22. The other end of the valve stem 62 passes through the guide sleeve 54 in the center of the cylindrical cavity 51 and abuts against the abutment part 45 of the switch handle 4. The upper end of the valve stem 62 extends into the limiting groove 46 of the abutment part 45. The entire valve body assembly 6 is in the state of closing the water outlet 52. The container is ready to store hot water and other heat-insulating liquids.

[0119] Pouring Water Operation: When the user needs to pour water, such as for making tea or coffee, they hold the grip part 32 with their hand. The curved structure of the grip part 32 fits the palm, providing a comfortable grip. Then, the user presses the pressing part 44 of the switch handle 4 with their finger. The switch handle 4 rotates around the hinge shaft 43, which moves downward along the mounting groove 27 on the mounting plate 26, causing the valve stem 62 to rise. The valve plug 61 leaves the lower opening of the cylindrical cavity 51, and the water outlet 52 opens. At this time, hot water flows out from the water outlets 52 on both sides of the cylindrical cavity 51. Due to the effect of the combined spout 3 guide part 33, the water flow is first dispersed to the central guide groove 332 and the side guide grooves 333 of the guide plate 331, and then converges into a uniform and stable water flow into containers such as teacups or coffee cups. The user can easily control the size and direction of the water flow according to their needs, avoiding hot water splashing and scalding or wetting the table.

[0120] When parents need to prepare formula for their child's breakfast, they can gently press the free end 41 of the switch handle 4. The spout 52 opens, and hot water flows out of the kettle. After passing through the guide channel, the hot water flows accurately into the bottle, avoiding the risk of scalding from spilled hot water. After pouring the water, releasing the switch handle 4 causes the valve stem 62 to descend under the weight of the valve plug 61 and the action of the spring (if present). The valve plug 61 then re-seals the spout 52, restoring the container to a sealed state and effectively maintaining the temperature of the internal liquid.

[0121] II. Outdoor Travel Application Scenarios

[0122] Adaptable to different containers: When traveling outdoors, if a non-original portable water bottle is carried, the bottle's opening diameter is compatible with the mounting section 313 of the mounting body 31 of the detachable insulated container of this invention. The user can remove the combined spout 3 from the original bottle body 1 (by reversing the installation steps, such as unscrewing) and then install it onto the portable water bottle. During installation, the limiting block 315 of the mounting section 313 engages with the water bottle opening, and the annular limiting retaining ring 314 and sealing ring 63 ensure a tight seal and secure connection.

[0123] After assembly, fill the water bottle with hot water or other beverages and close the lid 2. The cap 23 of the lid 2 prevents dust and other impurities from entering. During travel, when the user needs water, they can easily pour it out by pressing the switch handle 4, following the pouring procedure described above, without worrying about leaks or rapid temperature loss. Even in bumpy outdoor environments, the liquid inside the container is effectively preserved due to the tight connection between the lid 2 and the container, as well as the excellent sealing performance of the valve assembly 6.

[0124] Portability and Safe Use: The gripping part 32 plays a crucial role in outdoor use. When the user carries the container while walking or places it in a backpack side pocket, the connection assembly 7 (connecting block 71 and locking element 72) between the gripping part 32 and the bottle body 1 ensures a stable connection, preventing the spout or lid 2 from falling off due to shaking. Furthermore, the curved design of the gripping part 32 facilitates one-handed operation, allowing for quick and safe pouring when water is needed, meeting the portability and practicality needs of outdoor travelers.

[0125] III. Application Scenarios in Office Environments

[0126] Shared Use: In the office, detachable insulated containers are placed in the communal pantry. These containers can hold a large capacity of hot water or beverages such as coffee, allowing multiple colleagues to use them. The modular spout 3's flow guide 33 design allows different users to easily control the water flow when pouring, preventing a wet and cluttered desktop caused by multiple users.

[0127] For example, when a colleague finishes using the product, the switch handle 4 is turned off and the outlet 52 is sealed. When the next colleague comes to use the product, the temperature of the beverage in the container can still be maintained at a high level, reducing the energy consumption of frequent heating.

[0128] Cleaning and Maintenance: Due to its detachable structure, this invention is very convenient to clean. For regular cleaning, the upper cover 21 and lower cover 22 of the lid 2 can be separated for internal cleaning. The combined spout 3 can also be removed from the body 1 to clean the flow guide 33 and other parts, preventing the accumulation of scale and other impurities from affecting the flow and hygiene. The body 1 itself can also be easily and thoroughly cleaned, ensuring the container's long-term hygiene in the office environment and providing employees with healthy and convenient beverage services.

[0129] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0130] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
